Cloud-native architecture in software development refers to a design approach that leverages cloud computing principles, allowing applications to be built, deployed, and scaled in cloud environments. This architecture typically employs microservices, enabling independent deployment and scalability of different parts of an application. Using containerization, developers can package applications with their dependencies, ensuring consistent behavior across environments. Cloud-native architecture promotes resilience, allowing systems to recover automatically from failures. Moreover, it enhances collaboration and flexibility, as teams can rapidly develop and iterate on services, thus responding to changing business needs swiftly.
